Now and then I think of when we were together
Like when you said you felt so happy
You could die
Told myself that you were right for me
But felt so lonely in your company
But that it's love
And it's an ache I still remember

And it goes on, and on, and on
And on, and on, and on again

Rosemary, you're part of me
You are (you are, you are, you are)
Rosemary, you're part of me
You know (you are, you are, you are)
Are

Now and then I think of all the times you screwed me over
Had me believing it was always something that I'd done
But I don't wanna live that way
Reading into every word you say
You told that you could let it go
And I wouldn't catch you hung up on somebody
That you used to know

Rosemary, you're part of me
You are (you are, you are, you are)
Rosemary, you're part of me
You know (you are, you are, you are)

Rosemary, you're part of me
You know (you are, you are)

No, you didn't have to cut me off
Make out like it never happened
And that we were nothing
And I don't even need your love
But you treat me like a stranger
And that feels so rough

No, you didn't have to stoop so low
Have your friends collect your records
And then change your number
I guess that I don't need that though
Now you're just somebody that I used to know

Somebody that I used to know
Somebody that I used to know
Somebody that I used to know
Somebody that I used to know
